text: Bioinks are essential components of the bioprinting process. They are composed of living cells and enzymatic supplements to nurture an environment that supports the biological needs of the printed tissue. The environment created by the bioink allows for the cell to attach, grow, and differentiate into its adult form. Cell-encapsualting hydrogels are utilized in extrusion based bioprinting methods, while gelatin MethacryloylGelatin methacrylon (GelMA) and acellular comprised bioinks are most often used in tissue engineering techniques that require cross-linkage and precise structural integrity. It is essential for bioinks to help replicate the external cellular matrix environment that the cell would naturally occur in.
